Constructor Details

VariableCreator

public VariableCreator(AbstractVariable varDecl,
 IConfigurationElement parent,
 boolean isVisible,
 boolean isAttribute)

Sole constructor for this class.

Parameters:

varDecl - The specification of the variable which should be created

parent - The parent this variable is part of, typically the Configuration instance, but in case of compounds also the containing DecisionVariable

isVisible - Specifies whether this variables is exported by an interface or not:

• true: The variable is exported by an interface or there is no interface.
• false: There is an interface which does not export this variable.

isAttribute - whether a variable represents (as part of) an attribute or an usual variable shall be created

Method Details

getVariable

public IDecisionVariable getVariable()
                              throws ConfigurationException

Returns the created variable.

Returns:

The DecisionVariable representing the given AbstractVariable.

Throws:

ConfigurationException - in case that the types of AbstractVariable and DecisionVariable do not comply

getVariable

IDecisionVariable getVariable(boolean setDefaultValue)
                       throws ConfigurationException

Return the IDecisionVariable as in getVariable(). However, during the initialization of NestedVarConfigProvider the usage of the DefaultValueSetter will cause NullPointerExceptions. Therefore, this method with setDefaultValue = false should be used inside the initialization of nested IDecisionVariables.

Parameters:

setDefaultValue - true if the default value should be set for the newly created IDecisionVariable, otherwise false.

Returns:

The IDecisionVariable representing the given AbstractVariable, which was created by running the constructor of this class.

Throws:

ConfigurationException - in case that the types of AbstractVariable and DecisionVariable do not comply
